The 6’10” Northeastern University student also competed in the Henley Royal Regatta where the Boston eight-man team finished runners-up.

Chair of Sportscotland, Louise Martin, praised Buchan, and all the Scots selected in the rowing squad: “Congratulations to all of our Scottish rowers.

“After last summer’s terrific Olympic gold medals for Heather Stanning and Katherine Grainger, it is wonderful to see talented Scottish rowers coming through the system and competing at the highest level.”

Oarsman Buchan was in seat five of the GB eight-man boat in races. He actually defeated his GB team-mates in the semi-final at Henley while representing his college in the Challenge Plate final.

Selection marks a meteoric rise for Buchan who has also played for the Scottish basketball team. It was on a basketball scholarship when his potential as a rower was identified. That led to a move from prep school in the USA to Northeastern University where his boat career has rode the crest of a wave.

His ex-coach John Bunyan praised the 20-year-old, whose sister Mairi is also a Scotland and GB basketballer.

“What Cammy has achieved is nothing short of unbelievable!” he told The Falkirk Herald.

“He was a Scotland and GB squad member at basketball and then to be plucked from one sport while in the States on basketball scholarship to win another at a top US college for rowing and then row at Henley and then for Great Britain in the World Championships is nothing short of fantasy.

“ Cammy did a bit of rowing training on the machines during strength and conditioning with Fury but to go to potential Commonwealth Games status for Scotland in 2014 and the Olympics in 2016 is fantastic .

“As a club we are all very proud to have played a part in his athletic development”.
